Catalog Lint reads your product catalogue and tells you what is missing or duplicated, then gets out of the way. It holds no write permission, so it cannot edit or delete a product. Shopify shows you before you install: View, yes. Edit, no. Free checks your 50 newest products. Pro checks the whole catalogue, exports CSV and shows what changed since your last scan. We store no data. On Pro, a summary of your last scan stays in your own browser. No access to customers or orders.

• Nine checks: missing SEO, images, main-image alt text, SKUs and duplicates
• Read-only: it holds no write permission, and we store none of your data
• Every result links straight to that product in your Shopify admin
• Pro: export the full list as CSV, generated in your browser
• Nothing to configure and nothing to learn: one button
